BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to systems for providing vertically disposed spacedivision systems and, more particularly, to a flexible system whichemploys lightweight and rapidly reconfigurable elements with internalstretch characteristics, and with material support linkage means forproviding pivoted reconfigurations of spaced elements.

2. Background Art

Building infrastructure continue to evolve in today's commercial,industrial and office environments. For purposes of description in thisspecification, the term “commercial interiors” shall be used tocollectively designate these environments. Such environments mayinclude, but are clearly not limited to, retail facilities, medical andother health care operations, educational, religious and governmentalinstitutions, factories and others. Historically, infrastructureconsisted of large rooms with fixed walls and doors. Lighting, heatingand cooling (if any) were often centrally controlled. Commercialinteriors would often be composed of large, heavy and “stand-alone”equipment and operations, such as in factories (e.g., machinery andassembly lines), offices (desks and files), retail (built-in countersand shelves) and the like. Commercial interiors were frequentlyconstructed with very dedicated purposes in mind. Given the use ofstationary walls and heavy equipment, any reconfiguration of acommercial interior was a time-consuming and costly undertaking.

In the latter part of the 20th century, commercial interiors began tochange. A major impetus for this change was the need to accommodate theincreasing “automation” that was being introduced in the commercialinteriors and, with such automation, the need for electrical power tosupport the same. The automation took many forms, including: (i)increasingly sophisticated machine tools and powered equipment infactories; (ii) electronic cash registers and security equipment inretail establishments; (iii) electronic monitoring devices in healthcare institutions; and (iv) copy machines and electric typewritersrequiring high voltage power supplies in office environments. Inaddition, during this period of increased automation, otherinfrastructure advancements occurred. For example, alternative lightingapproaches (e.g., track lighting with dimmer control switches) andimproved air ventilation technologies were introduced, thereby placingadditional demands on power availability and access.

In recent decades, information technology has become commonplacethroughout commercial interiors. Computer and computer-relatedtechnologies have become ubiquitous. As an example,computer-numerically-controlled (CNC) production equipment has beenapplied extensively in factory environments. Point-of-sale electronicregisters and scanners are commonplace in retail establishments.Sophisticated computer simulation and examination devices are usedthroughout medical institutions. Increased sophistication of computer ??electronics associated with the examination devices is particularlyincreasing rapidly, with regard to the greater use of “noninvasive”procedures. Modular “systems” furniture has evolved to support thecomputers and related hardware used throughout office environments. Theproliferation of computers and information technology has resulted notonly in additional demands for power access and availability, but alsoin a profusion of wires needed to power and connect these devices intocommunications networks. These factors have added considerably to thecomplexity of planning and managing commercial interiors.

The foregoing conditions can be characterized as comprising: dedicatedinterior structures with central control systems; increasing needs forpower and ready access for power; and information networks and the needto manage all of the resulting wire and cable. The confluence of theseconditions has resulted in commercial interiors being inflexible anddifficult and costly to change. Today's world requires businesses andinstitutions to respond quickly to “fast-changing” commercial interiorneeds.

In general, these types of systems as developed over the past severaldecades can be somewhat characterized as permitting “partial”rearrangement of architectural interiors, and somewhat of an advancementin organizing interior space. Although the term “modular” is sometimesused to describe these types of systems, they did not fit within thetrue definition of a modular system. Instead, these systems areinherently “closed systems,” and are limited to finite sets ofinterchangeable physical parts.

With respect to all of the known space division systems, each suffersfrom a number of various disadvantages. For example, many of thearchitectural interiors in existence today actually result in an“overperformance.” That is, they have weight, bulk and other sizeparameters which are clearly unnecessary for their desiredfunctionality. Their cost is significant. This cost occurs not only frominitial acquisition prices, but also, as a result of their lack of trueflexibility, from costs associated with moving or reconfiguring theinteriors. Also, in part, additional costs result from the fact thatreconfiguration of such systems often results in wastes of componentparts. In this same regard, many component parts of known systems arenot reusable when disassembled.

Still further, known space division systems for many reasons (includingthose previously stated herein), do not lend themselves to any type of“rapid” reconfiguration. In fact, they may require a significant amountof work to reconfigure. This work often requires use of trainedspecialists. Also, reconfiguration of known space division systems mayinvolve additional physical wiring or substantial rewiring. Differenttrained specialists may be required when the reconfiguration in anymanner involves such electrical or data/communications components. Stillfurther, although these systems may involve lighting controllable by aworkspace user, many environmental functions remain centrallycontrolled, often in locations substantially remote from thearchitectural interior being controlled.

Other disadvantages also exist with respect to these known systems. Forexample, space dividers in use today are often “ground-based,” meaningthat they are supported and extend upwardly from floor structures. Manyof these configurations are limited in height, and do not particularlylend themselves to visual privacy. Also, as a result of the lack offlexibility and inherent problems with reconfiguration, known systems donot facilitate reconfiguration of space divider groupings, for purposesof individual privacy, collaboration and other “interaction”characteristics.

As earlier mentioned, known space division systems still do notparticularly assist in providing an occupant's control of his or her ownenvironmental conditions. Even further, however, difficulties can arisein known space division systems when environmental characteristiccontrol is provided within a general space of an occupant. For example,lighting associated with an occupant's usage area may be controlled by aswitch which is initially relatively close in proximity and readilyaccessible. However, if this interior space is reconfigured in anysubstantial manner, the switch controlling the lighting may no longer beaccessible or otherwise located in a functionally “correct” position. Inthis regard, known systems have no capability of providing anyrelatively rapid reconfiguration of controlling/controlled relationshipsamong functional elements, such as switches, task lights, data terminalsand the like. Also, to the extent these relationships are reconfigured,substantial rewiring by personnel having significant technical expertisewill be required.

Another significant disadvantage with known space divider systemsrelates to their lack of development in light of advances in technology.However, many of these technological advances have modified today'sbusiness, educational and personal work practices. Two examples ofrelatively recent technological advances consist of the semiconductorrevolution and the corresponding miniaturization of numerous electricaland data/communications components. Today, the work practices of manyindividuals involve the use of laptop computers and other portable,electronic devices. Many of these devices have the capability ofoperating on DC power. However, most of today's space division systemsdo not provide for availability of such power. In addition, knownsystems do not provide any other features which will facilitateefficiency in today's new work practices, such as ready access to datastorage and the like.

The foregoing is only a brief description of some of the disadvantagesassociated with current development in architectural interiors and spacedivision systems. In part, disadvantages exist because of today'sbusiness practices. The following paragraphs briefly describe otheraspects of today's activities in the areas of architecture and design,and why the foregoing disadvantages of known systems are becoming evenmore important.

In the past, problems associated with difficulty in reconfiguration ofarchitectural interiors, and lack of in situ control of a location'senvironmental conditions, may not have been of primary concern. However,today's business climate often involves relatively “fast changing”architectural interior needs. Architectural interiors may bestructurally designed by designers, architects and engineers, andinitially laid out in a desired format with respect to lightingfixtures, switches, data lines, and other functional accessories.However, when these structures, which can be characterized as somewhat“permanent” in most buildings (as described in previous paragraphsherein), are designed, the actual occupants may not move into thebuilding for several years. Designers need to “anticipate” the needs offuture occupants of the building being designed. Needless to say, insituations where the building will not be commissioned for several yearsafter the design phase, the architectural interior of the building maynot be appropriately laid out for the actual occupants. That is, theprospective tenants' needs may be substantially different from thedesigners' anticipated ideas and concepts. However, as previouslydescribed herein, most architectural interiors permit littlereconfiguration after completion of the initial design. Reconfiguring ofstructures in accordance with the needs of a particular tenant can beextremely expensive and time consuming. During structural modifications,the architectural interior is essentially “down” and provides nopositive cash flow to the buildings' owners.

It would be advantageous to always have the occupants' activities andneeds “drive” the structure and function of the architectural interiorlayout. To date, however, many relatively “stationary” (in function andstructure) interiors essentially operate in reverse. That is, it is notuncommon for prospective tenants to evaluate a building's architecturalinteriors and determine how to “fit” their needs (workspaces, conferencerooms, lighting, heating, ventilation and air conditioning (“HVAC”)requirements and the like) into the existing architectural interiors.

Still further, and again in today's business climate, a prospectiveoccupant may have had an opportunity to be involved in the design of abuilding's architectural interior, so that the interior isadvantageously “set up” for the occupant. However, many businessorganizations today experience relatively rapid changes in growth, bothpositively and negatively. When these changes occur, again it may bedifficult to appropriately modify the architectural interior so as topermit the occupant to expand beyond its original architectural interioror, alternatively, be reduced in size such that unused space can beoccupied by another tenant.

The foregoing paragraphs describe reconfiguration as a result of delaytime between original design and the time when users actually occupyspace, as well as situations where reconfiguration is required as aresult of a business organization's growth or other “external”conditions requiring reconfiguration. In addition, it would also beadvantageous to reconfigure architectural interiors substantially on a“real time” basis, where the needs of the occupants change almostinstantaneously. That is, the time period required for reconfigurationneed not be of any substantial length of otherwise involve changes in abusiness climate for a particular occupant.

As an example, it may be advantageous for the occupant of a particulararchitectural interior to have a specific layout during morning andevening hours, while having a revised layout during mid-day hours. Thiscould occur, for example, in an educational learning center, where usageof the architectural interior by students may change, for example, fromprimarily “individual” usage in the morning and evening hours, to jointprojects and meeting activities requiring collaborative usage duringmid-day hours. For such usage, it may be particularly advantageous tohave the capability of rapidly modifying interconnections of individualspace dividers, providing projection services, and facilitatingrelocation of laptops, task lighting and the like.

Other problems also exist with respect to the layout and organization oftoday's architectural interiors. For example, and as earlier describedherein, accessories such as switches and lights may be relatively “set”with regard to locations and particular controlling relationshipsbetween such switches and lights. That is, one or more particularswitches may control one or more particular lights. To modify thesecontrol relationships in most architectural interiors requiressignificant efforts. In this regard, an architectural interior can becharacterized as being “delivered” to original occupants in a particular“initial state.” This initial state is defined by not only the physicallocations of functional accessories, but also the control relationshipsamong switches, lights and the like. It would be advantageous to providemeans for essentially “changing” the relationships in a relatively rapidmanner, without requiring physical rewiring or similar activities. Inaddition, it would also be advantageous to have the capability ofmodifying physical locations of various functional accessories, withoutrequiring additional electrical wiring, substantial assembly ordisassembly of component parts, or the like. Still further, it would beadvantageous if users of a particular area could effect controlrelationships among functional accessories and other utilitarianelements at the location of the architectural interior itself.

DETAILED DESCRIPTION OF THE INVENTION

The principles of the invention are disclosed, by way of example, in aspace division system 600, incorporating technology. The space divisionsystem 600 utilizes a series of movable and internally reconfigurablevertically disposed partitions for purposes of providing lightingaesthetics, function signaling, privacy, semi-private configurations andthe like. In addition, the space division system 600 in accordance withthe invention also provides a space division system which facilitatesincorporation of various technologies. Space dividers and other aspectsof the space division system 600 in accordance with the invention arecapable of physical relocation, and comprise lightweight components.Rapid addition/deletion of joined space dividers is provided, throughthe use of quick-release components.

Still further, space division systems in accordance with the inventioncan comprise integration of solid state lighting (SSL). This lightingcan be utilized for functions such as providing for color changes ofspace dividers themselves. Still further, lighting functions can providefor the signaling of interior or exterior circumstances. For example,lighting associated with the space dividers can be utilized to providewayfinding. Signaling can also be utilized to indicate, for example,that a person is “in” within a particular working space.

Space division systems in accordance with the invention can alsocomprise integration and distribution of power. In particular, spacedivision systems in accordance with the invention provide for DC powerdistribution.

With respect to specifics of space division systems in accordance withthe invention, they can include channel voids within space dividers.These voids can be utilized to carry power lines, lighting, digitalstorage and other components.

Still further, space division systems in accordance with the inventionprovide for modification and reconfiguration of the appearance of spacedivider fabrics. Color change can be provided, for example, through theuse of solid state lighting embedded within channel voids of the spacedividers. In addition, appearance changes can be made to occur throughthe use of functional control of conventional lighting.

Space dividers employed in space division systems in accordance with theinvention can also provide for acoustical ameliorations. For example,space divider fabrics can employ physical sound attenuation material.Also, components associated with the space division system can providefor functional control of sound management systems and the like.Further, a primary aspect of space division systems in accordance withthe invention relates to the totality of the foregoing principles.

For purposes of describing the space division system 600 in accordancewith the invention in detail, reference is first made to a spacedivision system 100 as described and illustrated in FIGS. 1-51. Thisparticular space division system 100 was previously disclosed in aco-pending international PCT application entitled ceiling system withtechnology, filed Sep. 4, 2003. The space division system 600 inaccordance with the invention is described after the description of thespace division system 100, and is illustrated in FIGS. 52-78.

Turning to FIG. 1, the particular example of a space division system 100illustrated therein shows a space divider 102 vertically suspended froma rail system 104. The rail system 104 includes a rail 106 with a pairof hanger clips 108 which are releasably secured to the rail 106 andcapable of being moved along a continuum of the length of the rail 106.Support rods 110 depend downwardly from the hanger clips 108 and aresecured to the space divider 102. Preferably, the support rods 108 areadjustable in length so that the height of the space divider 102 mayalso be adjustable. Connection of the support rods 110 to the spacedivider 102 may be accomplished by any number of suitable means. Forexample, the lower terminating ends of the support rods 110 may belocated within grommet holes (not shown) at the top portion of the spacedivider 102. Such grommet holes may be spaced apart in a manner so as toprovide variation in the location of interconnections of the supportrods 110 to the space divider 102.

As earlier stated herein, the hanger clips 108 can be characterized as“quick release” and “quick connect” elements. That is, the hanger clips108 are advantageous for rapidly reconfiguring the physical locations ofspace dividers 102 relative to the rail system 104. General conceptsassociated with the rail system 104, and more specific configurations ofelements such as the hanger clips 108, are disclosed in the commonlyassigned U.S. Provisional Patent Application Ser. No. 60/408,149,entitled “Rail System” and filed Sep. 4, 2002.

The space divider 102 may include an upper structural batten 112. Theupper structural batten 112 provides, in part, for “shape holding” ofthe space divider 102. Extending downwardly from the structural batten112 is the main body 114 of the space divider 102. The main body 114 maybe of a fabric which is substantially opaque, so as to generally providea visual privacy curtain. Associated with the main body 114 is lightingtechnology, which may be in the form of solid state lighting (SSL)technology, such as LED lights. For example, embedded within the mainbody 114, in a manner so as to be visible to a person near the spacedivider 102, are a series of LED lights 116 arranged in a horizontalconfiguration. Further solid state lighting, which may also be in theform of LED lighting, is structured as arrow lighting 118 shown near thebottom of the main body 114. In emergency situations, the arrow lighting118 may be activated (in any of a number of appropriate controlarrangements) so as to activate all of the arrow lights 118 or,alternatively, the arrow lights 118 may be activated in a manner so thatthey are sequentially “pulsed” so as to create the effect of “pointing”in a particular direction to show an appropriate direction of egress inan emergency situation.

In addition to the concept of using arrow lighting 118, other types offunctional signaling can be provided. For example, solid state lightingor other types of lighting could be utilized in combination with otherelements so as to signal various other internal and external situations.For example, solid state lighting associated with the space dividers 102could be utilized to indicate if an individual is “in” a particularworkspace or, alternatively, is absent. Numerous other types ofsignaling could be utilized with the solid state lighting associatedwith the space dividers 102.

The space divider 102 also includes a lower hemmed section 120 having aweighted insert as described in subsequent paragraphs herein withrespect to other drawings. The weighted insert within the lower hemmedsection 120 may also be utilized for purposes of “shape holding.” Withrespect to the rail 106, hanger clips 108 and support rods 110, varioustypes of configurations may be utilized. One type of configuration isdisclosed in the commonly assigned U.S. Provisional Patent ApplicationSer. No. 60/408,149, entitled “Rail System” and filed on Sep. 4, 2002.

FIG. 2 illustrates a plan view of an office environment showing variousconfigurations of space dividers of a space division system according tothe invention, in differing configurations. For example, FIG. 2illustrates use of a wall curtain 130 having somewhat of a “hooked”configuration. A further space divider 132 is illustrated as showing aseries of “S-shaped” configurations, which may be utilized to provide aseries of computer workstations or the like. Conference tables 134 areillustrated as being somewhat enclosed through the use of the spacedividers 130, 132.

In addition to the foregoing, space divider 136 is shown as primarilyenclosing a privacy station 138, which may be utilized for telephonecalls or the like. Other areas may be partitioned or otherwise havespace dividers of the space division system in a manner so as to provideaesthetics, such as space dividers 140 and 142. The variousconfigurations of the space dividers illustrated in FIG. 2 can providefor various types of spaces. With the interconnection of space dividerssuch as 130, 132 and 140, 142, the interconnections can be providedthrough the use of splines. The spline interconnections are illustratedwithin the drawings. With the spline interconnections, reconfigurationsof the various space dividers is not limited to movement along specificline segments. Instead, with the use of the splines, movement can occurwith respect to the space dividers and the configurations toconfigurations having a curve of any reasonable radius.

FIG. 3 illustrates a side-elevation view of a space divider inaccordance with the invention. FIG. 4 illustrates a partial sectionalend view of the same. With reference to FIGS. 3 and 4, the space divider150 may be comprised of a translucent and stretchable material. FIG. 4illustrates how the material 152 may be woven into the wallconfiguration. The space divider 150 may also have a power batten 154positioned at the top thereof, for purposes of carrying power such aslow voltage DC power. The power batten 154 may provide power to a DCpower cable 156 or, alternatively, an AC power cable 158. The DC powercable 156 may carry DC low voltage power and is accessible through powerbatten openings 160. The power batten openings 160 would be accessibleto internal linear voids existing within the three-dimensional knittingof the main body 150. The linear voids are illustrated as voids 162 inFIGS. 3 and 4.

FIG. 5 illustrates another space divider 170 which may be formed of awoven fabric material. For example, one type of woven material which maybe utilized is commonly referred to in the industry as “cattle mattress”material. The cattle mattress material of the space divider 170 provideslinearly directed pockets 172 which may be segmented by the use ofbrackets 174, as illustrated in FIG. 6.

FIG. 7 is a perspective view of two curved space dividers, forming aspace division system 180. The space division system 180 includes afirst space divider 182 and a second space divider 184. In general, FIG.7 illustrates a structural configuration which may be achieved withrespect to aesthetic curvature, through the use of the space dividers182, 184. Also, FIG. 7 illustrates use of not only the rails 106, butalso the use of a cross rail 186. The configuration of a cross rail 186,with the use of vertically disposed partitions, is described in thecommonly assigned U.S. Provisional Patent Application Ser. No.60/408,149, entitled “Rail System” and filed on Sep. 4, 2002.

FIG. 8 illustrates a sectional end view of the space divider 184. Thisview shows the structural batten 112 at the top end thereof, with thefabric extending downwardly therefrom. Linear or substantiallyhorizontal voids 188 are provided at spaced-apart intervals downwardlyalong the space divider 184.

The space divider 184 terminates at its lower portion with the lower hem120. The lower hem 120 is shown as having a weighted insert 190. Theweighted insert 190 is utilized to maintain the space divider 184 in astable position. That is, the weighted insert 190 provides for “shapeholding” for the space dividers of the space division system 100. In aparticular example illustrated in FIG. 8, the weighted insert 190 may bea tubular section 192 fitted within the hem 120, and filled withmaterial such as sand.

FIG. 8A is similar to FIG. 8, but shows the lower hem 120 as capturing atubular insert 192. The tubular insert 192 may be a flexible sheath 194consisting of rubber or the like. The sheath 194 may be of relativelysubstantial weight in and of itself or, alternatively, may be weightedby the use of sand or other materials carried within the sheath 194. Theweighted insert 192 can include an end tab 196 which may beinterconnected to a cooperating recess or similar connecting means inthe weighted insert 192 associated with an adjacent space divider 184.In this manner, the weighted inserts of adjacent space dividers may beinterconnected together.

FIG. 9 is a sectional end view (taken along section lines 9-9 of FIG. 7)showing an end portion of the space divider 184. In this particularconfiguration, a power batten 200 extends downwardly so as to form anend hem of the space divider 184. A low voltage DC power cable 202 maybe extended downwardly through the power batten 200. In addition, it isalso possible to extend a communication cable 204 through the batten200. The batten 200 is formed by taking the space divider 184 andturning it rearward upon itself, and then connecting the end of thespace divider 206 to another portion of the space divider 184 throughthe use of a spring clip 208 or a similar releasable securing means.

FIG. 10 illustrates an interconnection between the space divider 182 and184 which may be employed in accordance with the invention. In thisparticular embodiment, a power batten 210 (having communication cables204) is formed at the intersection of the space dividers 182 and 184.The space dividers 182 and 184 are releasably coupled together throughthe use of a pair of spring clips 208.

In accordance with the foregoing, the space division system 100 inaccordance with the invention provides for the rapid addition anddeletion of space dividers. In addition, the elements of the spacedivision system 100 exhibit internal stretch characteristics, withrespect to space divider surfaces, battens and frames. These internalstretch characteristics provide for a continuum of configurations, withthe spline interconnections providing for curvature of any reasonableradius.

FIG. 11 is a close up section of the end portion of the space divider184, similar in form to FIG. 9. However, FIG. 11 further illustrates theuse of 3D translucent material for the space divider 184. Further, FIG.11 illustrates communication cables 212 which may extend through apre-woven pocket 214 of the translucent space divider 184.

FIG. 12 illustrates a “close up” view of the intersection between thespace dividers 182, 184. FIG. 12 is a view similar in scope to FIG. 10,but further illustrates power/communication cables 216 extending throughpre-woven pockets 218 of the space dividers 182, 184.

FIG. 13 is a close up section view of an end portion of the spacedivider 184 (similar to FIG. 11), but illustrating the space divider 184as comprising a woven fabric material 220. Various types of wovenmaterials may be utilized as material 220. For example, in theparticular embodiment described and illustrated herein, the wovenmaterial 220 may be a material which is characterized as “cattlemattress” material. FIG. 14 is a close up section similar in scope tothe close up section illustrated in FIG. 12, but showing the two spacedividers 182, 184 as employing cattle mattress material 220.

FIG. 15 is an elevational view of space dividers 230. More specifically,the space dividers 230 include a series of internal linear voids 232through which linear LED lighting strips may be inserted. Referring toboth FIGS. 15 and 16, such an LED lighting strip is illustrated in FIG.16 as LED strip 234. LED strip 234 will have a sequential series of LEDlights 236 extending along the lighting strip 234. The lighting strip234 will be positioned within the linear void 232. For purposes ofcarrying other elements, such as power cables or communication cables,additional linear voids, such as linear voids 238 and 240, may also behorizontally located within the space dividers 230. FIG. 15 alsoillustrates the use of a series of LED power supplies 242 which may beconnected to LED power lines 234. In turn, the LED power lines 234 maybe connected in any appropriate manner to the LED lighting strips 236.Further, additional power may be provided, such as with the utilizationof a 12-volt DC utility power supply line 246.

The particular LED lighting strips 234 may comprise, for example, yellowlinear flex side LED lighting strips, having a configuration ofapproximately 2 inches by 24 feet. Other interconnections may also beemployed with the space dividers 230, such as Internet connections andthe like. FIG. 17 is a side elevational view of a similar set of spacedividers 250. The sections 250 are similar to the sections 230previously described with respect to FIG. 15. In addition, thesesections carry LED power supplies 242 and LED power lines 244, inaddition to a DC power line 246. However, as illustrated in FIG. 18, theLED lighting strips 260 are turned in a different direction from the LEDlighting strips 234 illustrated in FIG. 16. In this manner, the actuallight intensity and light diffusion at the opposing surfaces of thespace dividers 250 will be different than that of the sections 230.Further, FIGS. 17 and 18 illustrate the use of two LED lighting strips260.

FIG. 19 is a further embodiment of a pair of space dividers 270, withFIG. 19 showing a side elevational view thereof. With respect to FIGS.19 and 20, a series of LED power supplies 242 are shown, interconnectedto LED power lines 244. Correspondingly, a DC power line 246 is alsoillustrated. With the space dividers 270, linear voids 272 are provided,one of which carries an LED lighting strip 274 having the substantially“flat” configuration illustrated in FIG. 20. In this particularconfiguration, a differing light intensity and light dispersion will beseen on the left side surface of the space divider 270 (as viewed inFIG. 20), while a relatively opaque view will be found from the rightside of the space divider 270 (again as viewed in FIG. 20).

FIGS. 21, 22 and 23 illustrate similar space dividers utilizing LEDinternal lighting technology. FIG. 21 illustrates space dividers 290,having linear voids 292 positioned at the lower portion thereof. Asillustrated in FIG. 22, each of the linear voids 292 carries aflat-configured LED lighting strip 296 facing toward the left side ofthe space divider 290 illustrated in FIG. 22. Alternatively, FIG. 23 issimilar in form to FIG. 22, and illustrates the upper LEDflat-configured lighting strip 298 as facing to the right side of thespace divider 290, while the lower LED flat-configured lighting strip298 faces toward the left side of the space divider 290. Again, theparticular light intensity, diffusion and color “wash” which will beassociated with the space dividers 290 will be dependent upon thespacing and the configuration of the LED lighting strips. It should beunderstood that the lighting strip configurations described herein aremerely examples of those which may be utilized with a space divisionsystem in accordance with the invention. Numerous other LED lightingstrip configurations could be utilized, without departing from thespirit and scope of the novel concepts of the invention.

FIG. 24 illustrates a pair of space dividers 300 having a linear orhorizontal void 302 wherein an LED lighting strip 304 is embedded. TheLED lighting strip 304 includes a series of arrows which can be utilizedfor emergency directional lighting, and may be sequentially “pulsed” soas to illustrate a direction of egress for emergency evacuation. Forpurposes of emergency directional lighting, various additionalelectrical equipment may be required. For example, it is not uncommonfor electrical and other building codes and regulations to require theuse of separate power sources for emergency lighting. In such event,such power sources may be required to be electrically interconnectedwith the LED lighting strip 304. Also, the lighted arrows of the LEDlighting strip 304 may be utilized for purposes other than emergencies.As an example, the arrows of the LED lighting strip 304 may be utilizedto provide “wayfinding” for purposes of directing visitors to thecommercial interior to appropriate locations within the interior, aswell as for purposes of emergencies. Along with other appropriate powerand lighting equipment, the arrows of the LED lighting strip 304 may beutilized, for example, to direct visitors in a library to appropriatebook classification sections. Numerous other wayfinding uses may alsoemploy the use of arrows or similar directional indicators of the LEDlighting strip 304. For example, and as earlier mentioned, lighting maybe utilized for indication of external and internal situations. Forexample, lighting may be associated with the space dividers in a mannerso as to indicate whether an individual is “in” a particular workspace.

FIGS. 25 and 26 illustrate a pair of space dividers 310, with LEDlighting technology utilized externally of the space dividers 310. Morespecifically, the space dividers 310 include a curtain 314 mounted fromthe top portion of the space divider 310. Depending forwardly andhorizontally from the space dividers 310 is an LED lighting stripsupport 316, which may be appropriately secured to a linear void 312 ofthe space dividers 310. Positioned downwardly from the support 316 is aseries of LED lights. The LED lights may be of appropriate colors, andwill provide what may be characterized as an external “wash” and a color“wash” over the lower portion of the side surfaces of the space dividers310, below the curtain 314. This color wash can be modified in intensityand with respect to diffusion dependent upon the intensity and color ofthe LED lights 318, and of the particular materials from which the spacedividers 310 are constructed.

FIG. 27 illustrates a pair of space dividers 320 showing a low voltageDC power line 328, communications cabling 326, AC power 322 and AC powerline 324. The AC power line 324 terminates in a pair of electricalreceptacles 330. A computer 332 may be energized through the electricalreceptacles 330. Data and communication signals may be transmitted fromthe computer 332 through a communications signal junction box or modem334, and outwardly through the communications cabling 326. In thismanner, the space dividers 320 provide power and networking technology.FIG. 28 is a side elevational view of space dividers 340, similar instructure to the space dividers 320 illustrated in FIG. 27. In thisparticular instance, the space dividers 340 are illustrated showing useof wall-connected task lighting technology. The configuration employs atask light 342 illustrated in FIGS. 28 and 29. The task light 342utilizes low voltage DC power and LED lighting technology. Asillustrated in FIGS. 28 and 29, the LED task light 342 includes arectangular LED marker 344 at the terminus of the task light 342.Extending downwardly from the marker 344 is a rigid foam core 346. Therigid foam core 346 is adjacent a flexible joint 348. A fabric cover 350extends downwardly and angularly from the flexible joint 348. The fabriccover 350 is interconnected to an appropriate securing bracket 352,which is secured to the space divider 340 by appropriate means. Forexample, Velcro or a similar securing means could be employed. The tasklight 342 may be utilized to provide appropriate light for use of acomputer screen 354.

In addition to the foregoing, the space dividers and associated channelvoids can be utilized with data storage technology. For example, thecomputer 332 or other types of computerized or communications equipmentcould be releasably attached to a data storage device embedded withinvoids of the space dividers. These data storage devices could be in theform of disks or similar devices. Also, for example, data storage andprogramming devices such as microprocessors could also be embeddedwithin voids of the space dividers, for releasable interconnection toother types of equipment, such as sound management technology and thelike. With respect to all the foregoing, the space division system 100in accordance with the invention provides for actual data storageembodied and embedded within the space division system itself. In thismanner, the space dividers themselves are not merely fabrics withinframes having battens and the like, but are elements which takeadvantage of today's miniaturization and advancements in technology, soas to provide data storage, access to programmable devices and the like.

FIG. 30 illustrates a curved configuration of a space divider 360showing the use of the task light 342 therewith. FIG. 31 is anelevational view of a pair of space dividers 370, showing the use of DClow voltage technologies with a pair of task lights 342.

FIG. 32 illustrates another pair of spacedividers 380, showing the space dividers 380 in use in an officeenvironment with technologies. For example, this office environment mayinclude a telephone 382, MP3 player 384, laptop 386 and fan 388. FIG. 33illustrates another pair of space dividers 390, showing use withtechnology which may be associated with a temporary work or gatheringspace. For example, the configuration illustrated in FIG. 33 includes aphone 382, a set of wireless headphones 384, teleconferencing screen 386and various other accessories.

FIG. 34 is substantially similar to FIG. 2, but further illustrates theuse of a projector 400 in use with a screen 402 secured to the spacedivider 130. The foregoing drawings illustrate interconnections ofvarious types of technological and other functional accessories throughthe space dividers. Further, the drawings illustrate the use of velcroclips at attachment points. As earlier stated, data storage devices andswitches can also be employed with the space dividers.

Still further, other types of equipment may be utilized. For example,both wired and wireless headphones may be employed and energized throughthe DC power distribution systems. Still further, projection equipmentmay be utilized, with projection screens releasably attached to fabricsof the space dividers. This was illustrated with respect to projectorscreen 402, coupled to the space divider 130. Still further, however,projection may occur upon fabric surfaces of the space dividersthemselves. This can be provided through the use of monofilaments.

FIGS. 35, 36 and 37 illustrate alternative embodiments andconfigurations of space dividers 410, 420 and 430, respectively, andillustrate various plan views of these space dividers so as to providevisual privacy. These space dividers may be in the form of what ischaracterized as “technology curtains,” and create flexible spaces forindividual and small group uses. In addition, the enclosures provided bythese space dividers exhibit daily flexibility for project teams. FIGS.38 and 39 show other configurations of the technology curtains,identified as technology curtains 432 and 434. These technology curtainscan be characterized as being configured in a “flutter” formconfiguration. FIGS. 38 and 39 show two alternative embodiments of the“flutter” form configuration. With these configurations of thetechnology curtains, relatively more efficient place making is provided.In addition, these configurations essentially maximize characteristicswhich tend to be unique to “hung” fabric. These arrangements also afforda greater variety of space division, and also more or a greater spatial“sense.” In addition, these “flutter” form configurations create morereceptacle spaces than what are characterized as “booth” walls. The“flutter” form configurations also provide relatively greater flexibleniche scale. In general, the embodiments of FIGS. 35, 36 and 37 showmovement from “shared” to “separate” configurations. The enclosuresformed by the space dividers within these drawings provide forsubstantial flexibility for project teams and the like. Still further,the configurations in FIGS. 38 and 39 provide for individuals' spacealong edges, in addition to collective action. That is, adjacency isprovided, but with relatively more privacy.

FIGS. 40 and 41 illustrate technology curtain configurations 436 and438. These configurations may be characterized as “quad-place”configurations. In these illustrations, the spaces shown movecollectively to a less flexible, central passageway which grow so as toaccommodate group work. The configurations comprise technology curtainswhich would provide both visual privacy and sound absorption. Advantagesassociated with “quad-place” configurations relate to the responsivenessto fluid conditions of collaborative work practices. In addition, theseconfigurations provide daily flexibility for project teams, and can begrouped as “sub-centers” around what may be characterized as a “silentcenter.”

FIGS. 42, 43 and 44 illustrate the use of technology curtains 440, 442and 444, respectively, and exemplify what can be characterized as“triplace” configurations. These technology curtain configurationsprovide both visual privacy and sound absorption. Benefits includeresponsiveness to fluid conditions of collaborative work practices, inaddition to daily flexibility for project teams. In addition, thesetriplace configurations can be grouped as “sub-centers” around a silentcenter. More specifically, FIG. 42 illustrates a configuration havingthree spaces. Correspondingly, FIG. 44 illustrates a configuration withtwo spaces, while FIG. 43 illustrates a single space configuration.

FIG. 45 illustrates the actual use of a translucent space divider 450.

As earlier referenced herein, the space division system 100 withtechnology provides a means for facilitating control and reconfigurationof control relationships among various functional components which maybe utilized with the space division system 100. For purposes ofdescribing the concept of establishing controlling relationships amongvarious controlled and controlling components which may be associatedwith the space division system 100, reference is made to the commonlyassigned U.S. Provisional Patent Application Ser. No. 60/374,012,entitled “Switching/Lighting Correlation System” and filed on Apr. 19,2002. The contents of the aforedescribed patent application are herebyincorporated by reference herein.

In this regard, it is relatively apparent that it would be favorable toestablish control relationships among switches and lights, and have thecapability of reconfiguring the same. Other control relationships mayalso be worthwhile. For example, FIG. 46 illustrates a user employing acontrol wand 460 (to be described in subsequent paragraphs herein) forpurposes of establishing control of an LED lighting strip 462. FIG. 46also illustrates the location of a wall-attached task light 464. Theseelements are associated with a space divider 466. FIG. 47 is similar toFIG. 46, but further illustrates the user employing the control wand 460for purposes of establishing control of the task light 464. An exampleof the control wand 460 is illustrated in FIGS. 48, 49 and 50. Withreference thereto, the control wand 460 may be of an elongatedconfiguration. At one end of the control wand 460 is a light source 470which, preferably, would generate a substantially collimated beam oflight. In addition to light source 470, the control wand 460 may alsoinclude an infrared (IR) emitter 472, for transmitting infraredtransmission signals to corresponding IR receivers associated with theLED lights 462 or task light 464, in addition to switches or the likewhich may control these functional accessories.

The control wand 460 may also include a trigger 474, for purposes ofinitiating transmission of IR signals. Still further, the wand 460 mayinclude mode select switches such as mode select switch 476 and modeselect switch 478. These mode select switches may be utilized to allowmanual selection of particular commands which may be generated using thewand 460. The control wand 460 may also utilize controllers (not shown)or similar computerized devices for purposes of providing electronicswithin the wand 460 for use with the trigger 474, mode select switches476, 478, light source 470 and the IR emitter 472. As earlier mentioned,an example of the use of such a wand, with the attendant commands whichmay be generated using the same, is described in the commonly assignedU.S. Provisional Patent Application Ser. No. 60/374,012, entitled“Switching/Lighting Correlation System” and filed on Apr. 19, 2002.

Referring back to FIGS. 46 and 47, the user may employ the wand 460 totransmit signals to controllers (not shown) associated with the LEDlights 462 and task light 464. The capability of essentially“programming” controlled relationships among the various accessoriesassociated with the space division system 100 requires the capability oftransmitting and receiving communication signals among the variousfunctional accessories. In this regard, infrastructure systems may beemployed. An example of such an infrastructure system which may beemployed with the space division system 100 in accordance with theinvention is described in detail in the commonly assigned U.S.Provisional Patent Application Ser. No. 60/408,149, entitled “RailSystem” and filed on Sep. 4, 2002.

FIG. 51 is a perspective view of a particular configuration utilizingspace divider 500 in a curved configuration, with task lights 502. Suchan arrangement could be utilized within a library, study hall orrestaurant configuration. Also, mention should be made that spacedivider 500, as well as other space divider configurations illustratedand described herein, may be utilized with various types of ceilingstructures. One such ceiling structure is illustrated in the commonlyassigned U.S. Design Patent Application Serial No. 29/166,803, entitled“Design for Articulating Ceiling” and filed Sep. 4, 2002.

Various types of appliances and technologies may be utilized with thespace dividers of the space division system 100, in addition to thosethat have been expressly described in detail herein. For example, soundapparatus such as speakers and the like may be integrated into thevarious space dividers of the space division system 100. Such speakersmay be energized through power and communication sources describedherein, or through other energizing means, including batteries and thelike. Still further, the speakers could be selectively enabled asdesired, and controlled with the control wand 460 and control processesdescribed earlier herein.

Still further, noise masking processes could be employed with the use ofthese speakers, in addition to general acoustical control arrangements.Still further, the noise masking arrangements employing the speakerscould be integrated within a virtual structure associated with the spacedivision system 100. In general, various types of speakers, noisemasking, acoustical control and other equipment and processes could beemployed with the technologies of the space division system 100, andpowered with the method and apparatus described herein, as well as withother energizing arrangements (e.g. batteries).

Still further, the space dividers of the space division system 100 mayhave application in situations which require the employment of securitymeasures. In this regard, it may be advantageous to construct spacedividers of the space division systems with materials having asubstantial capability of resisting penetration. An example of one suchmaterial is known as Kevlar® brand fiber, with the term Kevlar® being aregistered trademark of E.I. duPont de Nemours and Company. Kevlar®brand fiber is p-phenyleneterephtalamide. Kevlar® brand fiber combinesrelatively high strength with light weight. Kevlar® brand fiber iswithin a family of nylon fibers known as Aramids. Specifically, and iswithin a polyamide, with amide groups attached at carbons 1 and 4. Forpurposes of security, various of the space dividers of the spacedivision system 100 may be constructed of Kevlar® brand fiber.

Still further, will respect to security and safety, the space dividersof the space division system 100 may be constructed of fire resistant orfire proof materials. One such material which also falls within thefamily of Aramids is known as Nomex® brand fiber. The term Nomex® isalso a trademark of E.I. duPont de Nemours and Company. Nomex® brandfiber is commonly utilized for purposes of making fire proof clothing.Unlike Kevlar® brand fiber, Nomex® brand fiber has amide groups attachedat carbons 1 and 3. It is not uncommon to construct materials which areblends of both Nomex® and Kevlar® brand fibers. It may therefore beadvantageous to construct the space dividers of the space divisionsystem 100 with materials employing Nomex® brand fiber or othermaterials having fire proof properties, in addition to Kevlar® brandfiber or other materials which substantially resist penetration.

Another configuration of the space division system 100 may also beimportant with regard to security and safety. Specifically, it may beadvantageous to incorporate means in the space division system 100 forreleasably securing space dividers and other elements of the spacedivision system 100 to a floor structure. Various types of securingmeans could be employed with the space dividers, lower battens and thelike. However, it would be preferable to insure that the means forsecuring elements of the space division system 100 to the floorstructure still permit release of these elements from the floorstructure without significant effort.

Turing to other apparatus and concepts which may be employed with aspace division system in accordance with the invention, the lightingconfigurations described herein (such as LED lighting strip 462, tasklight 464 and the like) may employ various types of controllingapparatus in the form of enabling switches for controlling the state ofthe lighting elements or other electrical apparatus, appliances,computerized equipment and the like. In this regard, various types ofswitches may be employed. These switches may be in the form ofconventional switches having differing spatial positions for “on” and“off” states. However, other types of switches may also be employed. Forexample, the space division system 100 in accordance with the inventionmay employ optical switches for controlling lighting elements,electrical appliances and the like. With respect to use of the controlwand 460 previously described herein, the switches may be associatedwith sensors which can detect spatial signals transmitted from the wand460. Further, physically operable switches such as pressure switches mayalso be employed. Still further, various types of motion sensing devicesmay be employed to enable and disable switches and associated equipment.These and other types of switches may also be employed with the use ofradio frequency identification (“RFID”) systems, whereby, for example,an individual entering a room with a specific RFID badge may causeswitches and their associated sensors to identify the individual andconfigure lighting elements and other equipment associated with thespace division system 100 to specific states. Still further, all ofthese types of switches and other controlling devices may becommunicatively coupled to a power and communications network associatedwith the space division system 100. Such a network is generallydescribed in the commonly assigned U.S. Provisional Patent ApplicationSer. No. 60/408,149, entitled “Rail System” and filed Sep. 4, 2002.

In summary, a space division system 100 has been disclosed whichprovides for movable and internally reconfigurable space dividers,incorporates various technologies and is not limited in size orexpansion capability. The system is internally reconfigurable, lightweight and employs quick-release elements. In this regard, joined spacedividers can be rapidly added and deleted, and the use of splinesprovides for movement from line segment configurations to configurationshaving a curve of any radius.

In the same regard, internal stretch characteristics are exhibited byspace divider surfaces, battens and frames. Digital storage is alsoprovided within voids of fabrics associated with the space dividers.Still further, digital programming and switching is also provided. Inthis manner, space division systems in accordance with the inventionharness the effect of miniaturization, through the embedment andintegration of electronic components. In addition, solid state lightingis integrated within the system, having capabilities such as changingcolor appearances of space dividers and the like. In addition, signalingof interior and exterior circumstances is provided. In the same regard,space division systems in accordance with the invention incorporateintegration and distribution of power, particularly DC power and theflexible use of 12-volt applications.

With regard to structure, channel voids are provided within spacedividers at differing heights. Space divider fabrics can be modified inappearance, such as providing color changes using solid state lighting.Color appearance can also be modified through the functional control ofconventional lighting. Space division systems in accordance with theinvention can also exhibit acoustical ameliorations, through the use ofphysical sound attenuation material, functional control of soundmanagement systems and the like.

As previously described, the space division system 100 was generallydisclosed in an International PCT Patent Application entitled CEILINGSYSTEM WITH TECHNOLOGY, and filed Sep. 4, 2003. The system of primaryinterest herein, in accordance with the invention, is referred to as thespace divider system 600, illustrated in FIGS. 52-78.

The space divider system 600 may be used with a structural channelsystem 606. A structural channel system which may be utilized asstructural channel system 606 is disclosed in a co-pending United StatesProvisional patent application entitled “POWER AND COMMUNICATIONSDISTRIBUTION USING A STRUCTURAL CHANNEL SYSTEM” and filed Aug. 5, 2004.The disclosure of the aforedescribed patent application is incorporatedby reference herein. This application will be referred to herein as the“channel system application.” Also, with respect to a particular supportrail described subsequently herein, such a support rail is disclosed indetail in a co-pending United States Provisional patent applicationentitled “VISUAL SHIELDS WITH TECHNOLOGY INCLUDING LED LADDER, NETWORKCONNECTIONS AND CONCERTINA EFFECTS” and filed Aug. 31, 2004. Thisapplication is incorporated by reference herein and will subsequently bedescribed herein as the “visual shield application.”

With respect to the space division system 600 as subsequently describedherein in accordance with the invention, the system 600 is advantageouswith respect to ease of use. Material support linkage assemblies 610 asdescribed herein allow the system 600 to be shaped in a desired form,and not in a predetermined shape. Spaced elements 602 associatedtherewith can be reshaped into various forms, and can be free-standing.Zipper connections allow for side sections 604 to be attached to oneanother on both sides of one length of the system, or in a contiguousmanner to adjacent side sections 604 on the same side, thereby providinggreater flexibility in space management. The zipper connections providefor universal attachment, and thus do not require different attachmentmethods upon reconfiguration. Vertical rods, such as the support poleassemblies 617 within the system 600, provide structural support.However, the pole assemblies and other supporting elements arerelatively light, compared to traditional materials such as drywall.Also, threaded end rods can provide further structural support, as theyare attached to elements of the structural channel system 606. These canbe reoriented easily by attaching connecting clamps at differentlocations along the structural channel system 606.

Also, although the space divider system 600 can be utilized incombination with the structural channel system 606, it can also be usedwith other structures. Again, attachments such as threaded rods, cablesor clamps can be utilized. In addition, floor supports may be utilized,which can be adjustable so as to compensate for uneven floors. Stillfurther, support rods can be “keyed,” so that they can be readilyassembled, but “locked” into position at the time of installation.

With respect to aesthetics, the side sections 604 can be replaced atwill, and are interchangeable, allowing for different colors on eachside, if desired. In this manner, an “open” system is provided. That is,the size of the space division system 600 can be increased or reduced,at will by the addition or deletion of spaced elements 602. Stillfurther, various types of materials may be utilized for the sidesections 604. For example, fiberglass covers may be utilized. Ifdesired, such covers (and covers constructed of other materials) thatutilize J channels and appropriate hooks. With the use of theseelements, a continuum appearance can be provided, with minimal aestheticdisruption from seams and the like. The J channel cover attachments canbe tensioned, in conjunction with torsion support provided by thevertical rods. This eliminates a “bunching” condition that typicallyoccurs on the inner curve of curvilinear fabric wall structures.Further, various cover materials can be employed, so as to providevarying aesthetic looks, such as opaque, translucent and the like.

Still further, the cover materials comprising the side sections 604 canprovide functions other than coverings and aesthetics. For example, theside sections 604 can comprise cover materials which are appropriate foruse as projection surfaces. Also, the surfaces can be such that lightingcan change the appearance of the space. Still further, the side sections604 can be constructed of varying heights, so as to meet therequirements of a particular space. In addition, it may be possible tostack space divider systems.

Still further, the use of the side sections 604 with the supportingassemblies and material support linkage assemblies can provide, ifdesired, for a continuous inner channel between opposing side sections604. These channels can be utilized for various technologies. Forexample, with the cover materials of the side sections 604 exhibiting atleast some translucency, lighting assemblies may be incorporated withinthe spatial areas between the side sections 604. Also, other equipment,such as acoustical speakers, may be attached to the side sections 604,with the second 604 cut at will for purposes of placement of thespeakers. Cabling can be routed essentially anywhere within the channelsbetween the side sections. Switches can also be placed and attached asdesired. In addition, it may be possible to employ digital connections(e.g. 100 watt, class 2) within the space divider system 600, utilizingtransformers connected to the structural channel system 606. In thismanner, power can be provided for devices such as laptop computers,wayfinding features and the like. Such connections and adaptations maybe undertaken by lay persons, and may not require an electrician.

With respect to economics, the space divider system 600 can be shippedin a manner so as to reduce shipping costs considerably, relative toshipping costs for conventional building wall materials. Also, the spacedivider system 600 can be essentially “rolled up” and stored when not inuse, in a manner so as to require minimal space. Further, the elementsof the space divider system 600, including side sections 604, can bereused. In contrast, demolition is sometimes required in conventionalbuilding instruction. The reuse of the elements of the space dividersystem 600 therefore reduces landfill costs versus conventionalmaterials.

With these concepts in mind, reference is first made to FIG. 52,illustrating the space divider system 600 utilized with a structuralchannel system 606. Details regarding the structural channel system 606can be found in the channel system application. The space divider system600 is essentially “hung” from the channel system 606. Only a relativelysmall number of elements associated with the structural channel system606 are illustrated in FIG. 52. Specifically, FIG. 52 illustrates a mainstructural channel rail 607. The structural channel rail 607 is alsoillustrated in a sectional, end view in FIG. 69. As shown in FIGS. 52and 69, the main structural channel rail 607 includes a pair of sidecovers 638 surrounding the opposing lateral sides of the main structuralchannel rail 607. The side covers 638 enclose the main body of thestructural channel rail 607, including two opposing side panels 640(primarily shown in FIG. 69). The structural channel rail 640 alsoincludes an upper portion 642. The main body of the structural channelrail 607 may be supported from a ceiling or other overhead structure(such as a building's I-beams and the like) through support rods 644.The support rods 644 are coupled to the main structural channel rail 607through suspension bracket assemblies 656. The particular configurationof these suspension bracket assemblies 656 and the operation thereof aredescribed in detail in the channel system application.

Carried within the structural channel rail 607 are what can becharacterized as modular plug assemblies 646. These modular plugassemblies 646 can be utilized to carry AC building power to variouslocations and equipment which may be associated with the space divisionsystem 600. In addition, the modular plug assemblies 646 can also beutilized to transmit communication signals throughout a digital networkwhich may be associated with the space division system 600. The signalscan be utilized to control relationships among various applicationdevices, such as switches, lights, projection screens, sound equipmentand others. The modular plug assembly 646 and the concepts associatedwith carrying AC building power and communication signals are describedin detail in the channel system application.

For purposes of example, FIGS. 52 and 69 also show other functionalelements of the structural channel system 606. For example, an elongatedwireway 648 is illustrated as being mounted above the structural channelrail 607. The wireway 648 may be an electrically isolating component forcarrying relatively high voltage wires 650. FIGS. 52 and 69 alsoillustrate a cableway 652, mounted above the rail 607 and laterally ofthe wireway 648. The cableway 652 may have a structure similar to thewireway 648, but may not necessarily have substantial electricalisolating properties, and may be used for carrying digital and other lowvoltage cables 654. The wireway 648 and cableway 652 are also describedin the channel system application, along with details associated withtheir interconnections to the suspension bracket assembly 656 and therail 607. In addition to the main structural channel rail 607, thestructural channel system 606 may also include other overhead supportingelements, such as the support rails 608. The support rails 608 areillustrated in FIG. 52, and can be interconnected to the structuralchannel rail 607 by any suitable means. One of the support rails 608 isillustrated in greater detail in FIGS. 67 and 68. Also, elementscorresponding to the support rail 608 are described in detail in thevisual shield application.

Although a particular structural channel system 606 is shown herein asbeing utilized with the space division system 600, it should beemphasized that concepts associated with the space division system 600in accordance with the invention (particularly with respect to thematerial support linkages described herein) are not limited to use withthe structural channel system 606. That is, the space division system600 in accordance with the invention may be utilized with other types ofsupporting systems. In fact, various configurations of the spacedivision system 600 in accordance with the invention may be utilized ina “free standing” mode.

The embodiment of the invention comprising the space divider system 600will now be described in greater detail. The space divider system 600,as shown in FIGS. 52 and 53, includes a series of spaced elements 602.The spaced elements 602 essentially comprise opposing fabric or similarcovers, characterized herein as side sections 604. The side sections 604can be characterized as comprising a first side section 603 and anopposing second side section 605. At the top and bottom portions of theside sections 604 are material support linkage assemblies 610. Thematerial support linkage assemblies 610 are specifically shown in FIG.53, and will be described in greater detail in subsequent paragraphsherein with respect to other illustrations. The material support linkageassemblies 610 form a principal basis for the invention. As furthershown in FIG. 53, the material support linkage assemblies 610 utilizedwith the space division system 600 include a lower material supportlinkage assembly 612 positioned near the bottom of the side sections 604(and therebetween), and an upper material support linkage assembly 614positioned adjacent the upper edges of the side sections 604. Thematerial support linkage assemblies 610, as also generally shown in FIG.53, are formed through the use of sets of adjustable links 616. Theseadjustable links 616 will be described in greater detail, with respectto other illustrations.

The support pole assemblies 617 will now be described, primarily withrespect to FIGS. 53-53R. As shown in FIGS. 53 and 53A, the spacedivision system 600 includes what can be characterized as the secondsupport pole assembly 620. This assembly will be described first, sinceit represents the “left-most” assembly in FIG. 53A, and the remainingsupport pole assemblies will be described as shown in FIG. 53A from leftto right. It should be noted at this time that the specific embodimentof the space division system 600 as illustrated in FIG. 53 is slightlydifferent than the view of the space division system 600 illustrated inFIG. 52. That is, in FIG. 52, first and second support pole assemblies618, 629, respectively, at one portion of the system 600 are illustratedas being connected at the upper portions thereof to the main structuralchannel rails 607. For this connection, a universal channel connector894 is utilized. This channel connector will be subsequently describedherein with respect to FIGS. 69 and 70. As an alternative, FIG. 53 (andFIGS. 53A-53R) illustrate a slightly different configuration, where theparticular spaced elements 602 shown therein comprise two in number andutilize a first support pole assembly 618, second support pole assembly620 and one intermediate support pole assembly 622. Also, FIG. 53Aillustrates the use of rod assemblies 625. Again, this is somewhat of adifferent configuration in that illustrated in FIG. 52, and is meant toillustrate the concept that various configurations of the spacedelements 602 can be utilized to form the space division system 600 inaccordance with the invention.

Again referring to FIG. 53A and the second support pole assembly 620shown on the far left side thereof, the support pole assembly 620extends upwardly and terminates in what can be characterized as an uppersupport tube assembly 658. The upper support tube assembly 658 isutilized to directly support the second support pole assembly 620directly from any supporting structure associated with the structuralchannel system 606. Details regarding the upper portion of the uppersupport tube assembly 658 are illustrated in FIG. 53D. As shown therein,a relatively conventional spring clip 664 may be secured at the top ofthe support tube assembly 658 to the upper portion of a threaded rod666. The spring clip 664 may be releasably secured to various types ofoverhead supporting elements. The threaded rod 666 extends downwardlyand terminates within a conduit 670. The conduit 670 may be of a tubularconfiguration, preferably electrically isolated (i.e. constructed ofsteel or other metallic components). The conduit 670 can extenddownwardly and may be utilized for purposes of carrying electricaland/or communication wires or cables from the structural channel system606 to the spaced elements 602. The threaded rode 666 may be threadablyreceived into an aperture (not shown) of a conduit cap 668, illustratedin the sectional view in FIG. 53D. In turn, the conduit cap 668 may haveinternal threads for purposes of securing the cap 668 to a threadedupper portion of the conduit 670. Although this configurationillustrates one embodiment of a means for supporting the space divisionsystem 600 from overhead supporting elements, and for providing a meansfor extending electrical and communication wires and cables from anoverhead system downwardly to the spaced elements 602 (in an isolatedmanner), various other configurations may also be utilized, withoutdeparting from the principal concepts of the invention.

The upper support tube assembly 658 extends downwardly and is secured toone end of one of the adjustable links 616, as primarily shown in FIGS.53 and 53E. This coupling of the second support pole assembly 620 withan adjustable link 616 of the upper material support linkage assembly614 is referenced in FIGS. 53 and 53E as the second pole/link connector672. With reference to not only FIGS. 53 and 53E, but also FIG. 53M, thesecond pole/link connector 672 is coupled at its upper end to theconduit 670 through a threaded cap 674. The threaded cap 674 is keyed atits lower end so as to appropriately receive an upper end 678 of thesecond lower support pole 660. Tabs 680 at the top portion of the secondlower support pole 660 can be inserted into keyed slots (notspecifically shown) in the threaded cap 674. A spacer 676 is positionedintermediate upper and lower portions of the adjustable link 616 towhich the second pole/link connector 672 is interconnected. The spacer676 receives the upper end 678 of the second lower support pole 660. Inaccordance with foregoing, the upper support tube assembly 658 isinterconnected with the second lower support pole 660, and the two areinterconnected to the left-most adjustable link 616 as illustrated inFIGS. 53 and 53A.

The second lower support pole 660 will now be described primarily withrespect to FIGS. 53K, 53L, 53M and 53N. With reference to thesedrawings, the second lower support pole 660 includes the upper conduitplug 678 as previously described herein. The upper conduit plug 678includes tabs 680. The upper conduit plug 678 can be plug welded orotherwise secured to the upper end of an elongated conduit pole 682. Atthe lower end of the conduit pole 682, a second conduit plug, referredto herein as a lower conduit plug 678, is coupled to the lower end ofthe conduit pole 682 and comprises the configuration and shape shown inFIG. 53N. In fact, the upper conduit plug 678 and the lower conduit plug686 can be the same component, with the lower conduit plug 678 alsohaving a pair of tabs 680 for purposes of keying the lower conduit plug678 into an appropriate securing connection. As with the upper conduitplug 678, the lower conduit plug 686 can be secured to the lower end ofthe conduit pole 682 by any suitable means, such as the plug welds 684illustrated in FIG. 53N.

Reference is now made to the circle 53H in FIG. 53A and FIG. 53H itself,which show the lower end of the left most second support pole assembly620. With reference primarily to FIG. 53H, and as previously describedherein, the conduit pole 682 is coupled at its lower end to the lowerconduit plug 686. The lower conduit plug 686 may be keyed intosupporting elements through the use of the tabs 680. The lower conduitplug 686 may also be threaded at its lower end, so as to receive acoupling nut 688. The coupling nut 688 may include a threaded apertureextending completely therethrough, so as to threadably receive, at itslower end, a leveling guide 690. These components of the second supportpole assembly 620 can be coupled to one end of the adjustable link 616illustrated in FIG. 53H, with the lower conduit plug 686 extendingbetween upper and lower portions of the adjustable link 616. Anelongated portion of the lower conduit plug 686 can be received throughan aperture within a spacer 676 and sized so as to snuggly fit betweenupper and lower portions of the end of the adjustable link 616. Theleveling guide 690 is a relatively conventional component, and may beused to appropriately level the space division system 600 for purposesof facilitating stability and support.

The space division system 600 illustrated in FIG. 53A also includes anintermediate support rod assembly 622. In the particular embodimentillustrated in FIG. 53A, the intermediate support rod assembly 622 can,in fact, be the same set of components as the second support poleassembly 620 previously described herein. Accordingly, the intermediatesupport pole assembly 622 will not be described in detail herein.

As further illustrated in FIG. 53A, the particular space division system600 shown therein includes a series of four rod assemblies 625. Theserod assemblies 625 provide intermediate lateral support along the lengthof the spaced elements 602. Details regarding each of the rod assemblies625 are illustrated in FIGS. 53A, 53I, 53J and 61C. FIG. 61C isessentially an enlarged and sectional view of FIG. 53I. With referencefirst to the lower ends of the rod assemblies 625, and with specificreference to FIGS. 53I and 61C, each rod assembly 625 includes anelongated frame rod 692. These elongated frame rods 692 are shown intheir entirety in FIG. 53A. Extending from a lower end of the elongatedframe rod 692 is a second conduit plug 694. The second conduit plug 694,as shown in FIGS. 53I and 61C, includes a clevis-like end 700 at theupper end of the second conduit plug 694. The clevis-like end 700 may besecured in any suitable manner to the lower end of the frame rod 692,such as by plug welding or the like. The second conduit plug 694includes an elongated portion 696 extending downwardly from theclevis-like end 700. The lower end of the second conduit plug 694 can bereceived within one of the coupling nuts 688. In turn, the coupling nut688 can threadably receive one of the leveling guides 690. The elongatedportion 696 of the second conduit plug 694 extends downwardly through alink mid-aperture 702 of one of the adjustable links 616. Tabs 698 canbe keyed into slots (not shown) associated with the adjustable link 616.These slots and the link apertures will be described in detail insubsequent paragraphs herein.

The upper end of the rod assembly 625, and its interconnection to anadjustable link 616 of the upper material support linkage assembly 614is illustrated in FIG. 53J. Therein, although not specifically shown indetail, the upper end of the elongated portion 696 can be attached toanother second conduit plug 694, and turned upwardly in a reverseconfiguration relative to the second conduit plug 694 located at thelower end of the frame rod 692. The upper second conduit plug 694 canalso include a clevis-like end 700 (not shown in FIG. 53J butcorresponding to the clevis-like end 700 shown in FIG. 53I). Anelongated portion 696 can extend upwardly from the clevis-like end 700,through a link mid-aperture 708. The upper second conduit plug 694 canalso include tabs 698 which are keyed into slots (not shown) of theadjustable link 616. The upper second conduit plug 694 can be secured tothe adjustable link through the use of a hex nut 704 and washer 706. Inthis manner, any of the rod assemblies 625 can be secured as“intermediate” supports for the space division system 600.

The first support pole assembly 618 will now be described with respectto FIGS. 53A, 53C, 53F, 53G, 53O, 53P, 53Q and 53R. The particular spacedivision system 600 illustrated in FIG. 53 includes one first supportpole assembly 618. The upper portion of the first support pole assembly618 comprises an upper support tube assembly 658. The upper support tubeassembly 658 corresponds to the upper support tube assembly 658previously described with respect to the second support pole assembly620 and the intermediate support pole assembly 622. Accordingly, theupper support tube assembly 658 utilized with the first support poleassembly 618 comprises a spring clip 664, threaded rod 666, conduit cap668 and conduit 670. These components were previously described herein,and illustrated in FIG. 53D with respect to the second support poleassembly 620. Turning to FIG. 53G, the lower end of the upper supporttube assembly 658 is releasably coupled to a first pole/link connector710. The first pole/link connector 710 has a configuration substantiallysimilar to the configuration of the second pole/link connector 672previously described herein with respect to FIG. 53E. However, as willbe apparent from subsequent description herein, the first pole/linkconnector 710 utilized with the first support pole assembly 618 iscoupled to what can be characterized as components extending laterallyoutward from the “right” side of one of the adjustable links 616. Incontrast, and as illustrated in FIG. 53, the second support poleassembly 620 utilizes a second pole/link connector 672 which couples thepole assembly 620 to components of an adjustable link 616 which extendlaterally outward from the “left” of the adjustable link 616, as viewedin illustrations subsequently described herein.

The first pole/link connector 710 is utilized to interconnect the uppermaterial support linkage assembly 614 to the upper support tube assembly658 of the first support pole assembly 618, and the first lower supportpole 662. Referring to the first lower support pole 662, the same isillustrated in FIGS. 53A, 53F, 53G, 53O, 53P, 53Q and 53R. Withreference to these drawings, it is apparent from the same that the firstlower support pole 712 is substantially similar to the second lowersupport pole 660. That is, the first lower support pole 712 comprises anelongated conduit pole 714. The elongated conduit pole 714 is similar tothe elongated conduit pole 682 of the second lower support pole 660previously described herein. The first lower support pole furthercomprises an upper conduit plug 716, similar to the previously describedupper conduit plug 678. The upper conduit plug 716 includes a set ofopposing tabs 722 (FIG. 53Q). The tabs 722 are adapted to be keyed intoslots within apertures extending through one end of an adjustable link616 to which the lower support pole 712 is connected. The upper conduitplug 716 can be plug welded or otherwise secured to the upper end of theelongated conduit pole 714. The plug welds are shown at locations 720 inFIG. 53R.

The lower end of the first lower support pole 712 is primarilyillustrated in FIGS. 53A, 53F, 53O and 53P. With reference primarily toFIG. 53F, the lower end of the first lower support pole 712 includes thelower end of the elongated conduit pole 714. Extending outwardly anddownward from the conduit pole 714 is a lower conduit plug 718. Thelower conduit plug 718 can correspond in size and structure to the upperconduit plug 716. Accordingly, the lower conduit plug 718 can includeplug welds 720 for securing the same to the elongated conduit pole 714.The lower conduit plug 718 extends downwardly through a first upperbracket 728 of the right-hand side of one of the lower ones of theadjustable links 616. These interconnections will be described ingreater detail herein. The lower conduit plug 718 also extends throughan aperture of a lower bracket 730 of the adjustable link 616. A spacer726 is positioned between the upper and lower brackets 728 and 730, andincludes an aperture through which the lower conduit plug is extended.The lower conduit plug 718 also includes tabs 722 which can be keyedinto slots within the lower bracket 730. A threaded cap is alsoutilized, as primarily illustrated in FIG. 53F. The upper end of thethreaded cap is threadably received onto a lower end of the lowerconduit plug 718. Correspondingly, a lower end of the threaded cap 724is threadably received in one of the leveling guides 690. Thecombination of the brackets 728 and 730 of the adjustable link 616,along with the lower conduit plug 718, threaded cap 724 and spacer 726can be characterized as a first lower pole/link connector 732.

Returning to the upper end of the first lower support pole 712, thecoupling of this pole 712 with the upper support tube assembly 658 and aright side adjustable link 616 of the upper material support linkageassembly 614 will now be described primarily with respect to FIG. 53G.The first pole/link connector 710 includes a threaded cap 734. As shownin FIG. 53G, the threaded cap 734 extends upwardly and is threadablyreceived at the lower end of the upper support tube assembly 658.Correspondingly, the lower end of the threaded cap 734 threadablyreceives the upper conduit plug 716 of the first lower support pole 712.The upper conduit plug 716 extends upwardly through an upper bracket 734and a lower bracket 740 of the right-most adjustable link 616 of theupper material support linkage assembly 614. The upper conduit plug 716also includes tabs 722 which will fit within slots associated withapertures extending through the brackets 738, 740. In accordance withthe foregoing, the first pole/link connector 710 can be characterized asincluding the brackets 738, 740, spacers 736 and threaded cap 734. Theforegoing discussion substantially describes in detail the support poleassemblies which may be utilized with the space division system 600 inaccordance with the invention. However, it should be emphasized thatthese supporting assemblies comprise only a single embodiment of thespace division system 600 in accordance with the invention. Otherconfigurations may be utilized without departing from the principalconcepts of the invention.

The use of the material support linkage assemblies 610 will now bedescribed, primarily with respect to FIGS. 54-62B. The material supportlinkage assemblies 610 are significant to the principal concepts ofspace division systems in accordance with the invention. In part, thematerial support linkage assemblies 610, with their adjustable links616, allow for various patterns to be formed of the space divisionsystem 600, and other space division systems employing the materialsupport linkage assemblies. Also, the material support linkageassemblies 610 provide a means for facilitating ease of use, withrespect to assembly, disassembly and storage. As earlier described, thelinkage assemblies 610 allow the system 600 to be shaped into desiredforms, and not necessarily in any predetermined shapes. Still further,the spaced elements 602 can be reshaped into various forms, and can befree-standing. Zipper connections allow for the side sections 604 to beattached to one another on both sides of one length of the system 600,or in a contiguous manner to adjacent side sections 604 on the sameside, thereby providing additional flexibility and space management.

As previously described herein, vertical support pole and rod assembliescan be utilized with the system 600, for purposes of providingstructural support and general stability. Still further, the materialsupport linkages in accordance with the invention provide means foradjusting the shapes and general configurations of the space division600, while firmly retaining releasable support of fabrics or othermaterials associated with the spaced elements 602. Still further, withthe configurations of the material support linkage assemblies inaccordance with the invention, the assemblies reduce the “bunching”effect which often occurs with materials, when space dividers are beingformed into various shapes, after being initially coupled to supportstructures when the fabrics and other materials are in a “straight line”configuration. Turning to the drawings, the material support linkageassemblies 610 and the illustrative embodiment of the space divisionsystem 600 in accordance with the invention comprise two support linkageassemblies, namely a lower material support linkage assembly 612 and anupper material support linkage assembly 614, as illustrated primarily inFIG. 53. As earlier described herein, each of the material supportlinkage assemblies 610 is constructed of adjustable links 616 which arereleasably coupled together and secured to fabrics or other materials ofthe side sections 604 as described in subsequent paragraphs herein. Asalso described in subsequent paragraphs herein, the adjustable links 616of each material support linkage assembly 610 can be “rotated” or“pivoted” relative to an adjacently coupled adjustable link 616, so asto form various and desired patterns for the spaced elements 602 of thespace division system 600. It should be noted that this feature providesfor substantially greater scope of space division system patterns(meaning various formations or configurations) than exist when thespaced elements 602 can only be rotated relative to adjacent spacedelements 602. Further, it should be noted that the degree of resolutionattained in terms of degrees and “smoothness” of curvature in thepatterns can be made dependent upon the sizes of the adjustable links616. That is, the greater the “link density” (i.e. the number ofadjustable links per length of side sections 604) the greater will bethe curvature resolution.

FIG. 54 illustrates one of the adjustable links, as it would be orientedto be used with the lower material support linkage assembly 612. Theseparate adjustable links 616 in FIG. 55 are also shown in anorientation for use with the lower material support linkage assembly612. This orientation also exists in other illustrations of theadjustable link 616. However, it should be noted that FIG. 59, which isa bottom plan view of the adjustable link 616, is shown in anorientation reversed from the orientation shown in the top plan view ofthe adjustable link 616 illustrated in FIG. 57. The example embodimentof the adjustable link 161 in accordance with the invention will firstbe primarily described with respect to FIGS. 54-60B. With referencethereto, the adjustable link 616 includes an upper section 752 primarilyhaving the shape illustrated in FIGS. 54 and 57. The upper section 752extends along the top edge of the adjustable link 616. The link 616 alsoincludes a lower section 754 (primarily shown in FIGS. 54 and 59) whichextends along the bottom edge of the adjustable link 616. Again, itshould be noted that if the adjustable link is utilized as a link withthe upper material linkage assembly 614, the upper section 752 will beat the bottom of the orientation of the link 616, while the lowersection 754 will be at the top of link 616.

The adjustable link 616 also includes a main central body 750. The maincentral body 750 is formed (as illustrated in FIG. 54) by a web assembly756 and formed on one end of the adjustable link 616. The web assembly756 can include an upper web 758, central web 760 and lower web 762. Theweb assembly 756 can be formed by an inner wall 764, an upperintermediate wall 766, a lower intermediate wall 768, the lower edge 770of the upper section 752, and an upper edge 772 of the lower section754.

Moving to the left side or left end of the adjustable link 616 asoriented in FIG. 54, the link 616 includes a second inner wall 774. Thesecond inner wall 774 is essentially a mirror image of the inner wall764. Extending further toward the left side of the adjustable link 616as viewed in FIG. 54 is a flexible indexing tab 776. As will bedescribed in subsequent paragraphs herein, the indexing tab 776 ispreferably constructed and configured in a manner so as to provide forsome flexibility at its leading edge 778. This flexibility permits theflexible indexing tab 776 to be utilized in conjunction with a ratchetassembly (described in subsequent paragraphs herein) for purposes ofproviding the capability of angular adjustment of one adjustable link616 relevant to adjacent adjustable links 616. In the particularembodiment illustrated in FIG. 54, the flexible indexing tab 776 is of aunitary configuration. For purposes of flexibility, the flexibleindexing tab 776 is positioned in a manner so that it is not directlyconnected to either the upper section 752 or the lower section 754. Inthe particular embodiment illustrated in FIG. 54, the flexible indexingtab 776 is secured (through pop rivets 780 or other connecting elements)to a brace 782 having a first face 784 and a second opposing face 786(see FIG. 60B). It should be noted at this time that, in accordance withthe invention, it is substantially preferable for the flexible indexingtab 776 to be constructed of a material and configured so as to besomewhat flexible and resilient. In this regard, it may be preferablefor the indexing tab 776 to be constructed of a plastic material. Thisflexibility will permit the adjustable link 616 illustrated in FIG. 54to be capable of pivotal rotation relative to an adjacent link 616 whichis rotatably coupled to the link 616 shown in FIG. 54 through theflexible indexing tab 776. This concept will be made more apparent insubsequent paragraphs herein. Correspondingly, the brace 782 may beconstructed of a metallic or similar relatively rigid material, so longas it is coupled to the flexible indexing tab 776 in a manner such thatthe resiliency of the indexing tab 776 is not substantially lessened byits connection to the brace 782.

Again with reference first to FIG. 54, and turning toward the right handside of the adjustable link 616 (as viewed in FIG. 54), the link 616includes a ratchet assembly 788. The ratchet assembly 788 includes apair of ratchets 790, referred to in FIG. 54 as an upper ratchet 792 anda lower ratchet 794. Although this corresponds to the configuration inFIG. 54, it should be remembered that if the adjustable link 616 isutilized with the upper material support linkage assembly 614, theratchets 792, 794 would be reversed in vertical disposition.

The ratchets 790 are primarily shown in FIGS. 54-60A. Each of theratchets 790 extends laterally outwardly from a pair of arms 796. Thearms 796 are connected to or are otherwise integral with the upper web758 and the lower web 762. Each ratchet 790 has a cylindricalconfiguration and forms what can be characterized as a cylinder portion798. Within each cylinder portion 798 is a recessed area 800 which isopen at one end of its corresponding ratchet 790. Specifically, therecessed area 800 of the upper ratchet 792 opens upwardly as viewed inFIG. 54. Correspondingly, the recessed area 800 of the lower ratchet 794opens downwardly as viewed in FIG. 54. Extending partially through therecessed area 800 of each of the ratchets 790 is a sleeve 806. Each ofthe sleeves 806 includes a throughhole 802 extending verticallytherethrough, as primarily illustrated in FIG. 58. Each of thethroughholes 802 include a pair of key slots 804. The throughholes 802,with their corresponding key slots 804, will be utilized to receive atabbed connecting pin 808, as illustrated in FIG. 55. The connecting pin808 is utilized to mechanically couple together adjacent links 616,while still permitting pivotal movement between the same.

At the outermost end of each of the ratchets 790 (as viewed at FIG. 54),a ratchet gear 810 is positioned. As shown particularly in FIGS. 56, 57,59 and 68, each of the ratchet gears 810 includes a set of ratchet teeth812 extending partially around the outer perimeter of the cylinders 798of the ratchets 790. The ratchet teeth 812 are oriented so that theteeth 812 themselves, and the gaps therebetween, are verticallydisposed.

As described in subsequent paragraphs herein, the ratchet teeth 812 ofone adjustable link 616 are adapted to engage the leading edge 778 ofthe flexible indexing tab 776 of an adjacent adjustable link 616. It isthis engagement between the teeth 812 of one adjustable link 616 and theflexible indexing tab 776 of another, adjustable link 616 which permitsthe pivotal movement of one of the adjustable links 616 relative to theother adjustable link 616.

Turning to other elements of the adjustable link 616, the inner wall 764and second inner wall 774 were previously described herein primarilywith respect to FIG. 54. These walls 764 and 774 form a spatial area 814therebetween. Correspondingly, the upper section 752 of the link 616also includes a middle spatial area 816. Further, the lower section 754also includes a centrally located spatial area 818. Extending upwardlyinto the spatial area 816 is an upper cylindrical sleeve 826. The uppersleeve 826 forms an upper keyed throughhole 820. Correspondingly, alower cylindrical sleeve 828 extends downwardly from the upper portionof the spatial area 818 of the lower section 754. This lower sleeve 828forms a lower keyed throughhole 822. Each of the throughholes 820, 822includes a pair of key slots 824, as shown in FIGS. 57 and 59. Thethroughholes 820, 822 and the spatial area 814 are adapted to receivethe elongated portion of the second conduit plug 694, previouslydescribed herein and illustrated in FIG. 53I. In accordance with theprior description, the second conduit plug 694 is utilized withcorresponding rod assemblies 625.

Returning to the left most portion of the adjustable link 616 as viewedin FIG. 54, the upper section 752 includes a spatial area 830, primarilyshown in FIGS. 57 and 58. Correspondingly, the lower section 754 alsoincludes a lower spatial area 832, primarily shown in FIGS. 58 and 59.With respect to the spatial area 830, a circular area 834 (FIGS. 57 and58) is formed therein at the left most end of the upper section 752.Formed at the lower portion of the circular area 834 is an upper sleeve836 having a cylindrical configuration. Formed within the upper sleeve836 is a keyed throughhole 838. Correspondingly, with reference to thelower section 754 and the spatial area 832, a lower sleeve 842 extendsdownwardly from an upper portion of lower section 754. Formed within thecylindrical lower sleeve 842 is another keyed throughhole 844. The keyedthroughhole 844 is vertically aligned with the keyed throughhole 838.Each of the throughholes 838, 844 include a pair of key slots 840.

The keyed throughholes 838 and 844, like the keyed throughholes 802associated with the ratchets 790, are adapted to receive a connectinglink or pin 808, as illustrated in FIG. 55. Further, as apparent fromthe foregoing description, when the adjustable links 616 are coupledtogether, the end of one adjustable link 616 having the ratchets 790 iscoupled to the end of the adjacent adjustable link 616 through its endhaving the keyed throughholes 838, 844 and the leading edge 778 of theflexible indexing tab 776. This connection arrangement is illustrated inFIG. 55.

In accordance with the foregoing description, when the adjustable links616 are coupled together, the coupling occurs not only through theconnecting links 808, but also through the gearing connections betweenthe ratchets 790 associated with one end of one adjustable link 616, andthe leading edge 778 of the flexible indexing tab 776 of the adjacentadjustable link 616. This concept is primarily illustrated in FIG. 52A,in the sectional plan view thereof. It should also be noted that theconnecting link 808 can include tabs which can be inserted into the keyslots 804 of the ratchets 790 and the key slots 840 of the keyedthroughholes 838 and 844.

Reference is now made to the coupling of the adjustable links 616 to thefirst support pole assembly 618, second support pole assembly 620 andintermediate support pole assembly 622. Also, as previously describedherein, the second support pole assembly 620 and the intermediatesupport pole assembly 622 are substantially the same. Accordingly, onlythe coupling between the second support pole assembly 620 and theadjustable link 616 will be described. More specifically, reference ismade to FIG. 61A, which illustrates the coupling of the first supportpole assembly 618 with an end adjustable link 616, where the link 616corresponds to the right most link 616. This configuration waspreviously described in detail with respect to FIG. 53F. In thatdescription, reference is made to the concept that the lower conduitplug 718 extends through the ratchets 790 of the end adjustable link616. Again, this coupling is described in detail with respect to FIG.53F.

Correspondingly, FIG. 61B illustrates the coupling of the second supportpole assembly 620 to the left most adjustable link 616 of the lowermaterial support linkage assembly 612. More specifically, FIG. 61Billustrates the coupling between the left most adjustable link 616 andthe elongated portion of the lower conduit plug 686. The coupling of thelower conduit plug 686 to the left most adjustable link 616 waspreviously described in detail with respect to FIG. 53H. Still further,FIGS. 61A and 61B illustrate the use of a keyed connector link 808 whichmay be utilized for purposes of coupling together two adjacentadjustable links 616.

Similar types of couplings are utilized for interconnecting the firstsupport pole assembly 618 and second support pole assembly 620 toadjustable links 616 of the upper material support linkage assembly 614.More specifically, the coupling between a left most adjustable link andthe second support pole assembly 620 is illustrated primarily withrespect to FIG. 53E, showing the coupling of the adjustable link 616 andthe upper conduit plug 678. Correspondingly, the coupling between thefirst support pole assembly 618 and the right most adjustable link 616of the upper material support linkage assembly 614 is primarilyillustrated in FIG. 53G. FIG. 53G illustrates the coupling specificallybetween the upper conduit plug 716 and the right most adjustable link616 of the upper material support linkage assembly 614.

FIGS. 62A and 62B specifically illustrate the concept of the use of amaterial support linkage assembly 610 and the capability of pivotalrotation of individual links 616 of the support assembly 610 relative toadjacent individual links 616. As previously described, FIG. 62Aillustrates the concept that when one adjustable link 616 is coupled toan adjacent adjustable link 616, the leading edge 778 of the flexibleindexing tab 776 of one of the adjustable links is engaged with theratchet teeth 812 of the two ratchet gears 810 associated with the pairof ratchets 790 of the adjacent adjustable link 616. Specifically, FIG.62A illustrates the “straight line” orientation of two adjacentadjustable links, with one of the links being shown in phantom lineformat. In solid line format, FIG. 62A illustrates the concept that bymoving one of the adjustable links 616 so that the leading edge 778 ofits flexible indexing tab 776 engages other teeth 812 of the ratchetgears 810, the adjustable links 616 can be rotated relative to eachother. FIG. 62B illustrates a particular configuration using a series ofadjustable links 616. It should be emphasized, and in accordance with aprincipal concept of the invention, that the flexible indexing tab 776should exhibit some flexibility and resiliency for the leading edge 778to be manually rotatable along the teeth 812 of the ratchet gears 810associated with the adjacent adjustable link 616. Further, it may bepreferable for the ratchets 790 having the coupled ratchet gears 810 toalso exhibit some flexibility or resiliency. Without the relativeflexibility or resiliency between the leading edge 778 and the ratchetgears 810, it would not be possible to move the leading edge 778 of theflexible indexing tab 776 from one set of ratchet teeth 812 to anotherset of ratchet teeth 812 of the adjacent ratchet gears 810. That is, ifthe leading edge 778 and the ratchet gears 810 were both completely“hard” and stationary, such movement would not be capable, in that theleading edge 778 or teeth 812 could not flex in a manner so as to permitmovement from one set of teeth 812 to another set of teeth 812.

Reference will now be made to concepts associated with the coupling ofside sections 604 to each other. Specifically, FIG. 63A illustrates aconfiguration where a first side section 603 is coupled at an end of amaterial support linkage assembly 610 to the opposing second sidesection 605 (not specifically shown). In this situation, and asillustrated in FIG. 63A, a zipper connection 846 is utilized. The zipperconnection 846 employs a conventional zipper 848. The zipper 848positioned at a terminating end of a pair of end pieces 850. The endpieces 850 are connected to the side sections 604 through any desiredmaterial connections 852. This concept of the use of the zipperconnection 846 to couple together opposing side sections 604 is alsoillustrated in FIGS. 66A and 66B.

A configuration is also illustrated herein with respect to couplingtogether side sections 604 which are adjacent and located on the sameside of the space division system 600. Such a configuration isillustrated in FIG. 63B and utilizes what is characterized as a secondzipper connection 854. Again, the second zipper connection 854 includesa zipper 848, with end pieces 850 attached to opposing ends of the pairof side sections 604. It should be emphasized that the side sections 604may be on either side or both sides of the space division system 600.The end pieces 850 are connected to the side section 604 throughmaterial connections 852, which may be any suitable type of connections.

Reference will now be made to the concept of coupling the side sections604 to the adjustable links 616. In this regard, FIG. 64 (a sectionalview from FIG. 63B) illustrates means for connecting the side sections604 to the adjustable links 616. As shown in FIG. 64, and with referenceto FIGS. 54, 55 and 57, along with FIG. 64, the adjustable links 616each include a material connector 856 on each side of the link 616. Asshown in these illustrations, when an adjustable link is used for thelower material support linkage assembly 612, the material connectors 856essentially form a J channel 858 which is open at its lower end.Correspondingly, as illustrated in FIG. 53, when an adjustable link 616is utilized as part of the upper material support linkage assembly 614,the J channel 858 of the material connectors 856 opens upwardly, due tothe reversal in orientation of the adjustable links 616.

Further, as illustrated, for example, in FIGS. 53 and 64, each of theside sections 604 can include a connector hook 860. Each connector hook860 can be in the form of an elongated material strip having a J hook862. In the adjustable links for the lower material support linkageassembly 612, the J hooks 862 open upwardly. When the connector hooks860 are utilized with the upper material support linkage assembly 614,the J hooks 862 open downwardly. As shown in FIG. 53, each of theconnector hooks 860 may be in the form of an elongated strip. Theconnector hooks 860 may be coupled to the fabrics of the side section604 through the use of connectors 864 or similar connecting means.Alternatively, the connector hooks 860 may, for example, have anadhesive backing which permits the connector hooks 860 to be adhesivelyattached to the side sections 604. FIG. 65 illustrates, in elevationview, the inside of a side section 604 showing the upper and lowerconnector hooks 860.

Reference will now be made to various connection arrangements betweenthe upper support tube assemblies 658 and various structural elementscomprising the overhead system to which the space division system 600 isconnected. This overhead system has been referred to herein as thestructural channel system 606. With reference to FIGS. 67 and 68, theupper support tube assemblies 658 can be coupled to overhead structuralelements characterized as support rails 866. These structuralconfigurations of the support rails 866 will not be described in detailherein. However, these support rails 866 are described in detail in thevisual shield application previously referenced herein, and incorporatedby reference herein. The visual shield application also describes theconcept of interconnection of the support rails 866 to the structuralchannel rails 606.

Turning again to FIGS. 67 and 68, the upper support tube assembly 658shown therein has a somewhat different upper configuration than as shownin FIG. 52, in that the configuration shown in FIG. 52 illustrates theuse of spring clip connections or similar connections 636. In thisparticular connector arrangement, a support rail connector 870 isutilized. At the upper aperture of the upper support-tube assembly 658is a threaded portion, in which a threaded support rod 868 may bereceived. The support rail connector 870 includes an L-shaped portion872 with a lower base 874. The lower base 874 can include an aperture(not shown) with a threaded bushing 892 positioned immediately above theaperture. The upper end of the threaded support rod 868 is adapted to bethreadably received within the aperture and the threaded bushing 892. Anut 886 is utilized to fix the position of the threaded support rod 868within the aperture and threaded bushing 892.

The L-shaped portion 872 includes a lower base 874, within which theaperture and threaded bushing 892 are positioned. The lower base 874 isintegral with a vertical leg 876 which extends vertically upwardly, andterminates in a lip 878. The lip 878 essentially curls around a supportrail leg 890 located on one side of the support rail 866. A separateelement characterized as a connector bracket 880 which still forms partof the support rail connector 870, is positioned as shown in FIGS. 67and 68, and is horizontally disposed. The connector bracket 880 includesa terminating and upwardly directing lip 894 which essentially“captures” a lower support rail base 888 above the connector bracket880. At one end of the connector bracket 880, a T-bar 882 extendsoutwardly through a T-slot 884 located in the vertical leg 876 of theL-shaped portion 872 (see FIG. 68). The interaction between the T-bar882 and the T-slot 884 limits the relative positioning of the connectorbracket 880 and the lower base 874. When the upper support tube assembly658 has been coupled to the support rail 866 as shown in FIG. 67, theconnection can be disassembled by first loosening the nut 886. After thenut is sufficiently loosened, the vertical leg 876 is free to movesufficiently downwardly, so that the T-bar 882 can be moved into theupper horizontal leg of the T-slot 884. With this movement, the T-bar882 can be removed from the T-slot 884, and the connector bracket 880can then be disengaged from the L-shaped portion 872. It should be notedthat this particular configuration represents only one embodiment of aconnection arrangement between the support rails 866 and the uppersupport tube assembly 658, and other arrangements can be utilizedwithout departing from certain of the principal concepts of theinvention.

Reference will now be made to connection arrangements between the uppersupport tube assembly 658 and direct connections to the structuralchannel rails 607. With reference specifically to FIGS. 69 and 70, andfirst referring to the exploded view of FIG. 70, a structural channelconnector assembly 894 is provided for use in connection of the uppersupport tube assembly 658 to the structural channel rail 607. Withreference first to FIG. 70, the structural channel connector assembly894 includes one L-shaped bracket 896 and a modified L-shaped bracket897. The L-shaped mounting bracket 896 includes a horizontal base 900having a substantially horizontal plane. In contrast, the modifiedL-shaped bracket 897 includes a modified base 901 which is substantiallyhorizontal but is in somewhat of a partial raised configuration asspecifically shown in FIG. 70. Other components of the L-shaped bracket896 and modified L-shaped bracket 897 are substantially the same, andwill be like-numbered.

Each of the horizontal bases 900, 901 includes a threaded aperture 902extending through the central portions thereof. Each L-shaped bracket896, 897 also includes a vertical leg 904 extending upwardly, andterminating at its side edges in a pair of spades 906. At the central,upper portions of the vertical legs 904 are curved portions 908, eachterminating in a lip 910. Each of the curved portions 908 also includesa modified T-slot 912 having a particular shape and configuration asillustrated in FIG. 70.

The structural channel connector assembly 894 also includes a separatecomponent, illustrated in FIG. 70 and identified as a connector 898. Theconnector 898 is a singular piece having a center raised portion 914.Vertical legs 916 extend upwardly from each end of the center raisedportion 914. Each of the vertical legs 916 terminates in a T-bar 918. Asshown primarily in FIG. 69, the structural channel connector assembly894 can be connected to a structural channel rail 607 by mating theL-shaped brackets 896, 897 together (as shown in FIG. 69) and thenthreadably engaging the threaded support rod 868 through the threadedapertures 902. The connector 898 can then be positioned so that theT-bars 918 extend upwardly through the modified T-slots 912. With thisconfiguration, the lips 910 of the curved portions 908 extend around andcapture elements of the structural channel rail 606 as specificallyillustrated in FIG. 69. The threaded rod 868 can then be broughtupwardly through the threaded apertures 902 sufficiently so as torigidly secure the structural channel connector assembly 894 to thestructural channel rail 607. When it is desired to disassemble theconnection between the rail 606 and the upper support tube assembly 658,the threaded rod 868 can be threadably disengaged from the apertures902, thereby permitting the L-shaped brackets 896, 897 to be movedupwardly a sufficient distance so as to disengage the curved portions908 from the structural channel rail 607. It should be emphasized thatdetails regarding the configuration of the structural rail 607 are setforth in detail in the channel system application.

The structural channel system 606 can also include other types ofsupporting rails, such as the supporting brace 920 illustrating in FIGS.71 and 72. Therein, a supporting brace 920 is illustrated, which may bea type of brace which is utilized with the structural channel system606. The supporting brace 920 includes a top portion 922, and a pair ofintegral downwardly projecting sides 924. At the bottom of the sides924, a pair of lips 928 curve back upwardly. The supporting brace 920can also include apertures in the top portion 922, for purposes ofrunning electrical wires, sprinkler systems or other devices downwardlythrough the supporting brace 920. One aperture 926 is partially shown inFIG. 72.

For connection, a brace connector assembly 931 is utilized with an uppersupport tube assembly 658 and the supporting brace 920. The braceconnector assembly 931 includes a horizontal base 932. The horizontalbase 932 includes curved end portions 934, which curve upwardly on eachside of the base 932. A separate mounting bracket 936 is also provided,with the configuration primarily shown in FIG. 72. The mounting bracket936 includes a pair of opposing downwardly curved portions 938. At thetop of the mounting bracket 936 is a threaded bushing 940. Although notspecifically shown in the drawings, the threaded bushing 940 ispositioned above a central aperture in the mounting bracket 936. Forpurposes of interconnection, the upper support tube assembly 658 caninclude a threaded rod 868 extending upwardly therefrom. The braceconnector assembly 931 can be positioned so that the threaded rodextends through a central aperture of the horizontal base 932 andupwardly through the aperture (not shown) in the mounting bracket 936.Further upward movement will cause the threaded support rod 868 to bethreadably received within the threaded bushing 940, as illustrated inFIGS. 71 and 72. A nut 930 can be utilized to fixedly secure thethreaded support rod 868 in a desired position, relative to the braceconnector assembly 931. This position, for securing the supporting brace920 to the threaded support rod 868 is illustrated, in particular, inFIG. 71. Therein, it is shown that the downwardly curved portions 938abut the inner portions of the upwardly turned lips 928 of thesupporting brace 920. In this position, the brace connector assembly 931is secured to the supporting brace 920. To disengage the brace connectorassembly 931, the nut 930 can be loosened, so that it is disengaged fromthe threaded bushing 940. Again, FIGS. 71 and 72 illustrate oneembodiment of a brace connector assembly 931 which may be utilized inaccordance with the invention. Numerous other connection arrangementsfor connection of the upper support tube assembly 658 to overhead systemelements of the structural channel system 606 or other overhead systemsmay be utilized, without departing from certain of the principalconcepts of the invention.

FIGS. 63A and 63B, as previously described herein, illustrate the use ofzipper connections 846, 854, respectively, at the ends of side sections604 and at mid points between adjacent side sections 604. FIG. 73 issubstantially similar to FIG. 63A, and illustrates the upper portion ofthe zipper connection 846 and the coupling of the configuration to anupper support tube assembly 658. Also shown therein, in a substantiallyenlarged view, is the adjustable link 616 located at that particular endof the configuration of the space division system 600.

As previously described herein, the space divider system 600 can beutilized in various formats. For example, FIG. 74 illustrates the spacedivider system 600 as having side sections 604 with a height Z. Based onthe sizes of the side sections 604, the height Z can be varied.Variations in the height of the side sections 604 will not necessarilyrequire the use of any different components with respect to the materialsupport linkage assemblies 610 or other components of the space divisionsystem 600. In this regard, the support pole assemblies 617 can be cutto desired heights, dependent upon the desired height Z.

Still further, FIG. 75 illustrates the concept of potentially “stacking”a pair of space division systems 600. More specifically, FIG. 75illustrates the use of the space division system 600 at a top portionand a second space division system 942 below the space division system600.

As will be apparent from the prior description herein, when the spacedivision system 600 is constructed, with the opposing side sections 603,605, a “void” area will be located between the side sections 603, 605,with the void having a depth which corresponds at least to the depth ofan adjustable link 616. FIG. 76 is a sectional, plane view of a void 944which may exist between two side sections 603, 605, with the adjustablelinks 616 therebetween. In such a void 944, various types of applicationdevices may be employed. For example, FIG. 76 illustrates the concept ofa flat panel display or flat panel speaker 946 which may be secured inany suitable manner within the void 944. If the side sections 604 aremade of a translucent material, the flat panel display 946 could beutilized to project images.

Also, for purposes of utilizing various types of electronic or otherelectrical devices with the space division system 600, a “subsystem” canbe utilized for purposes of application of low voltage power (DC orotherwise) to the space division system 600, for purposes of poweringvarious application devices. In this regard, reference is made to theblock diagram of FIG. 77, which illustrates the use of a DC subsystem948. More specifically, FIG. 77 illustrates the concept of receiving ACpower from an AC power network 950 on a power line 952. Conceptsassociated with distribution of AC power in an overhead electricalnetwork and structural channel system are described in detail in thechannel system application, previously referenced herein, andincorporated by reference herein. The AC power on power line 952 can beapplied as input to a conventional transformer 954. The transformer 954can be utilized to convert the incoming AC power to DC power. The DCpower can be applied as output power from the transformer 954 on DCpower lines 956. Such DC power lines 956 may be external to the uppersupport tube assembly 658 or, alternatively, may be run through thesupport tube assemblies 658 and through conduit pipes or tubesassociated with the support pole assemblies 617, such as pole assemblies618, 620. Still further, for purpose of distribution among the variousspaced elements 602 of the space divider system 600, the DC power lines956 can be applied through an electronic transfer hub 958 to DC sublines960. The DC sublines 960 can then be appropriately connected, by anyconventional means, within the voids 944 (or outside of the voids) ofthe space divider system 600. In this manner, low voltage power (DC orotherwise) can be distributed throughout the space divider system 600.

In addition to utilization of electronic elements within the void 944(as illustrated in FIG. 76), the side sections 604, which may compriseof fabric material, can be cut so that other electronic elements can beutilized with the space divider system 600. For example, FIG. 78illustrates a plan view of a pair of side sections 603, 605 showing thevoid 944 therebetween, and showing an example of an adjustable link 616also positioned therebetween. An opening 964 has been cut into thematerial of the first side section 603. A conventional speaker 962 isextended through the opening 964, as illustrated in FIG. 78. The speakercan be connected to electronic wires or other components through, forexample, the DC subsystem 948 previously described herein with respectto FIG. 77.

A number of concepts associated with the invention have been describedherein. With respect to the material support linkage assemblies 610,various principal concepts of the invention are associated. For example,with the use of flexibility and the couplings between leading edges 778and ratchet gears 810, adjacent adjustable links 616 are capable ofpivotal rotation relative to each other. Still further, if fabric orother types of materials which exhibit at least a minimum of stretchproperties are utilized for the side sections 604, variousconfigurations of the space division system 600 can be achieved, withoutthe conventional problems of “bunching” of materials. This advantageexists in substantial part because of the configurations and conceptsassociated with the material support linkage assemblies 610 (with theirattendant adjustable links 616) and the means for coupling the materialsof the side sections 604 to the adjustable links 616.

It will be apparent to those skilled in the pertinent arts that otherembodiments of space division systems in accordance with the inventionmay be designed. That it, the principles of space division systems inaccordance with the invention are not limited to the specificembodiments described herein. Accordingly, it will be apparent to thoseskilled in the art that modifications and other variations of theabove-described illustrative embodiments of the invention may beeffected without departing from the spirit and scope of the novelconcepts of the invention.
